I'm a "casual" bluetooth user. I purchased the 2500 to use on my 45 minute commute each way, and occasionally when I am inside and need to talk hands-free. I've been pleasantly surprised how far I can walk away from my BB and still get decent reception. For me the 2500 is fine. Very inexpensive; sounds clear; despite what another post said I don't notice it on my ear. I'm sure there are better ones out there but it meets my needs. Only complaint--for my first call when I get in the car the 2500, doesn't automatically "connect'--I have to press a button by the mouthpiece. I assume this is what one post was referring to. Don't know if other bluetooth headphone users have to do this. In any event it is not a big deal.
